  • DPCCH bursts are control signals that enable a UE to be synchronized or connected with a network.
  • the UE is allowed to send the DPCCH in bursts periodically to maintain synchronization or a connection with the network.
  • DPCCH bursts is conventionally configured by higher layers.
  • bursty transmissions may include data transmissions that are sent in short bursts, and in between the bursts are gaps when no data is sent at all.
  • bursty transmissions may include data transmissions that are sent in short bursts, and in between the bursts are gaps when no data is sent at all.

  • TD Time Division
  • One problem with existing CPC is that, when the DPCCH burst is sent according to a pre-determined pattern, the UE has no idea whether it is going to experience a lot of interference from other UEs, or if it will experience no interference at all. If there is a lot of interference from other users during the burst, the inner loop power control in the network measures a low Signal to Interference Ratio (SIR), which will cause the UE to increase DPCCH power. When the UE transmits data again, it can transmit with too much power wasting power and causing interference in the network, especially if there is no other user interference with the data transmission.
  • SIR Signal to Interference Ratio
  • a second problem is that when the DPCCH burst is transmitted, the burst may collide with other user data
  • CPC provides the bursts, and also DPCCH preambles (prior to a user transmitting data) and DPCCH post ambles (transmitted just after a user transmits data), as illustrated in Fig. 1.
  • a Lean Carrier solution proposes to completely remove the DPCCH bursts, and also DPCCH pre-ambles and post ambles, to remove the interference problems associated with them, as discussed above, and, in general, to reduce interference in the network.
  • the Lean Carrier solution aims to minimize control signaling.
  • a UE is given a grant when it needs to send data.
  • DPCCH bursts and DPCCH preambles can be a problem.
  • the bursts, particularly pre-ambles can be useful for power control and channel tracking for a user, if the interference experienced by the bursts is similar to the interference that will be experienced when the user transmits data.
  • the DPCCH bursts can be a problem if the bursts and pre-ambles/postambles are interfered with by another high rate user, and in a second case, if the bursts interfere with high rate users.
  • CPC has no way to distinguish when a DPCCH burst will be useful or harmful.
  • the Lean Carrier solution completely removes bursts and, therefore, cannot take advantage of when they might be useful without some modifications. In the Lean Carrier solution, the UE must always transmit data together with the DPCCH burst.
